高桩台碼头現有的計算方法大都忽略桩两端的固接影响,假定它为鉸接。这类計算方法的共同缺点,是歪曲了实际上是固接构造的結构内力的分布情况,同时不能用来分析只有垂直桩的桩基的高桩台碼头,而这种桩基布置,由于預应力鋼筋混凝土桩及大型管桩的出現,已經得到采用。安东諾夫提出的能够精确考虑桩端固接影响的方法,計算又較繁。本文提出用初参数法进行計算,可以精确地考虑桩端的固接影响,計算亦較簡便。同时还給出了考虑切力影响的必要公式。文末有例題說明該法的具体运算步骤。
The existing calculation methods for high-pile wharfs mostly ignore the fixed joint effects at both ends of the pile, assuming it is articulated. The common disadvantage of this type of calculation method is that it distorts the distribution of the internal forces of structures that are actually fixed structures, and it cannot be used to analyze high-pile quays with only vertical pile foundations. The emergence of prestressed reinforced concrete piles and large pipe piles has been adopted. The method that Antonov proposed to accurately consider the effect of fixed end of the pile is more complicated. This paper proposes to use the initial parameter method to calculate, can accurately consider the impact of the fixed end of the pile, the calculation is also relatively simple. At the same time, the necessary formula to consider the influence of the shear force is also given. At the end of the text, there are examples to illustrate the specific operation steps of the law.
